Wasp nest in a/c unit, how would you deal with it?

Plastic or garbage bag and bug bomb would be the least "interesting" but we all have good wasp stories, so maybe make it something a little more risky for the entertainemrnt value! Lol

Also it's a wives tale that they don't fly at night. They will get you and you can bet that they are all at home waiting vs in the day where a bunch are gone at any given time.
